Hi,

I'm trying to modify the code below to use. Basically, it's a simple form a user is required to fill-out. When the form is filled and submitted a button will appear, if the form is not filled or submitted a text reading "Fill the form" will show. I need help with the button showing part I was hoping someone here could help out. My knowledge of PHP is below basic.


The HTML Form

HTML Code:
<form action="result.php" method="post" class="niceform">
	<fieldset>
    	<legend>Pet's Information</legend>
        <dl>
        	<dt><label for="name">Name:</label></dt>
            <dd><input type="text" name="name" id="name" size="32" maxlength="128" /></dd>
        </dl>
        <dl>
        	<dt><label for="location">Location:</label></dt>
            <dd><input type="location" name="location" id="location" size="32" maxlength="32" /></dd>
        </dl>
    </fieldset>
    <fieldset class="action">
    	<input type="submit" name="submit" id="submit" value="Submit" />
    </fieldset>
</form>



The PHP Code

PHP Code:

<?php  
if(isset($_POST['submit']))
{   
  if(
$_POST['name'] && $_POST['location'])
  {
    
$file fopen("black_listed_words.txt"'r');
    if(
$file)
    {
  
$blacklisted_array explode(",",fgets($file));
  
$input $_POST['name'].' '.$_POST['location'];
  
$input_words explode(" "$input);
  
$result array_intersect($blacklisted_array$input_words);
  if(
$result)
  {
  echo 
'you have entered a blacklisted word.';
  }
  else
  {
  
fclose($file);
  
$file2 fopen("input_info.txt"'a');
  
$input_info "$input\r\n";
  
fwrite($file2$input_info);
  
fclose($file2);
  echo 
'Login successful. Click here to continue <form action=""><input type="submit" value="Enter" /></form>';
  }
    }
    else
    {
  echo 
'No such file exists.';
    }
  }
  else
  {
    echo 
'Please fill in both fields before submitting the form.';
  }
}
?>

When a user successfully submits the form above a button will appear here linking to an external page. On the external page are some basic text with something basic like

PHP Code:
This is the result for <strong><?php echo $_GET["name"]; ?> located in <strong><?php echo $_GET["location"]; ?></strong>
